質問 # 19
A user needs to determine known security vulnerabilities on an existing BIG-IP appliance and how to remediate these vulnerabilities. Which action should the BIG-IP Administrator recommend?
正解：D
解説：
F5 recommends using the iHealth diagnostic tool to identify security vulnerabilities and receive specific remediation guidance.
* QKView and iHealth: A QKView file is a comprehensive diagnostic snapshot of the BIG-IP system.
When this file is uploaded to the F5 iHealth portal, it is automatically parsed against a database of known issues and security advisories.
* Vulnerability Diagnosis: The iHealth platform includes automated checks specifically designed to surface security gaps and "Heuristics" that match the system's current configuration and software version to known CVEs (Common Vulnerabilities and Exposures).
* Remediation Guidance: For every identified vulnerability, iHealth provides direct links to the relevant F5 Security Advisory (K-article), which contains detailed remediation steps, such as specific software versions that contain a fix or temporary mitigation commands.
* UCS vs. QKView: While a UCS (User Configuration Set) file is a backup of the system configuration, it is not the format used by the iHealth diagnostic engine for automated vulnerability scanning; the QKView is the required format for this process.
質問 # 20
Refer to Exhibit. An organization is reporting slow performance accessing their Intranet website, hosted in a public cloud. All employees use a single Proxy Server with the public IP of
104.219.110.168 to connect to the Internet. What should the BIG-IP Administrator of the Intranet website do to fix this issue?
正解：B
解説：
This scenario describes a classic network performance issue known as the "Mega-Proxy" problem. When an organization routes all employee traffic through a single proxy server, the BIG- IP sees thousands of unique users as having the exact same source IP address. If the administrator has configured "Source Address Affinity" persistence, the BIG-IP will correctly follow the rule but incorrectly route all users to the same single backend pool member. This creates a severe load imbalance where one server is overwhelmed while others remain idle, leading to poor application response times. To resolve this, the administrator must change the persistence profile to "HTTP Cookie". Cookie-based persistence allows the BIG-IP to place a unique identifier in each user's browser, allowing the system to distinguish between individual sessions even if they share the same source IP. This fix ensures that traffic is distributed evenly across the pool members, restoring the expected load balancing functionality and resolving the slow performance reported by users behind the corporate proxy.
質問 # 21
A BIG-IP Administrator adds new Pool Members into an existing, highly utilized pool. Soon after, there are reports that the application is failing to load for some users. What pool level setting should the BIG-IP Administrator check?
正解：A
解説：
When troubleshooting a pool that is not working correctly after adding new members, the "Slow Ramp Time" setting is a primary suspect. In a pool that is already under high load and using a "Least Connections" load balancing method, a newly added server has zero connections. Without a slow ramp time, the BIG-IP will immediately direct a massive flood of new connections to the new server to "balance" it with the others. This
"thundering herd" effect can crash a newly initialized application server before it has time to warm up its caches or establish its own database connections. By setting a "Slow Ramp Time" (typically in seconds), the administrator ensures the BIG-IP gradually increases the connection ratio to the new member. This allows the server to stabilize and scale up its performance over time. If users report intermittent failures specifically coinciding with the expansion of a pool, checking this setting is a vital troubleshooting step to maintain pool health during maintenance.
質問 # 22
Refer to the exhibit.
A BIG-IP Administrator needs to deploy an application on the BIG-IP system to perform SSL offload and re-encrypt the traffic to pool members. During testing, users are unable to connect to the application.
What must the BIG-IP Administrator do to resolve the issue? (Choose one answer)
正解：C
解説：
To successfully perform SSL offload and re-encryption on a BIG-IP system, the virtual server must be configured with both a Client SSL profile and a Server SSL profile. The Client SSL profile enables BIG-IP to decrypt inbound HTTPS traffic from clients, while the Server SSL profile is required to re-encrypt traffic before forwarding it to the pool members.
From the exhibit, the virtual server has a Client SSL profile configured, which allows BIG-IP to accept HTTPS connections from clients. However, there is no Server SSL profile attached, meaning BIG-IP attempts to send unencrypted HTTP traffic to pool members listening on HTTPS (port 443). This protocol mismatch causes the server-side SSL handshake to fail, resulting in users being unable to connect to the application.
This behavior is well documented in BIG-IP SSL troubleshooting guides: when backend servers expect HTTPS, a Server SSL profile is mandatory to establish a secure connection from BIG-IP to the pool members.
The other options are incorrect:
Removing the Client SSL profile (Option A) would break client-side HTTPS.
The server-side TCP profile (Option B) is unrelated to SSL encryption.
Forward Proxy (Option C) is only used for outbound SSL inspection scenarios.
Therefore, configuring an SSL Profile (Server) is the correct and required solution.
質問 # 23
Due to a change in application requirements, a BIG-IP Administrator needs to modify the configuration of a Virtual Server to include a Fallback Persistence Profile. Which persistence profile type should the BIG-IP Administrator use for this purpose?
正解：D
解説：
Persistence is critical for ensuring that a client's session remains with the same pool member throughout its duration. If primary persistence (like Cookie Persistence) fails--for instance, because the client has disabled cookies--load balancing will not work as expected, and the session may be broken. A "Fallback Persistence Profile" provides a backup method. The most common and reliable fallback method is "Source Address Affinity". This method tracks the client's IP address in the BIG-IP's persistence table and ensures that any subsequent requests from that IP are routed to the same pool member, even if the primary persistence token is missing.
Troubleshooting session drops often involves checking if a fallback method is configured to handle scenarios where the primary method is unsupported by the client's browser or environment. Without a fallback, the BIG-IP would revert to standard load balancing, potentially sending the client to a different server that lacks their session data.
